More reasons why I call bull**** on Blythe being planned from the get-go:
-Could have been released literally days after Three Houses was released worldwide; wasn't. Time frame wise, Blythe should have been 2 and Hero should have been 3 but they weren't.
-Koei Tecmo literally helped develop Three Houses but Blythe has no Tecmo Mii costumes or Fire Emblem Mii costumes? That's super suspicious.
-Keep in mind that with the previous two points in mind, Sakurai would have had to have finalized the plans for the Fighter's Pass in early November 2018. Sakurai himself shared that Joker, Hero, and Banjo were all being worked on in December. Why would a first party character, especially one for an upcoming summer release be pushed to the very back of the Fighter's Pass? Again, if always planned, Byleth would have been like Roy and Corrin and released super close to releases of their respective games. Byleth was released half a year later, significantly later than the peak sales of the game. With this in mind, Hero was still released BEFORE Dragon Quest XI S so still counted as a promotional character. Smash characters encourage sales. From a business standpoint, it makes no sense especially since the Smash fanbase has been pretty adamant about not wanting more Fire Emblem characters.
Again, I call bull****. Sakurai's a smart man and too many decisions made are the polar opposite in regards to this character. Great addition but if you try to convince me that a very obvious promotional character missed the game's release by half a year, is sandwiched with major third party icons, includes no Mii costumes related to it despite being first party, and was originally going to totally close off DLC despite overwhelming evidence that this would have been a catastrophic decision, I can't take that seriously. Blythe isn't unbelievable but all the circumstances surrounding him definitely are.
There's also no reason for this character to be kept this hard of a secret either for a mountain of reasons outside of knowing people would be pissed. Nintendo KNEW 5 was probably going to land like a wet sock because there was literally no reason to tell us there was going to be more DLC after 5 a full four and a half months before even revealing them. They could have done it during this presentation and that's the elephant in the room. The Fighter's Pass was naturally announced after the base roster was revealed, Season 2 was formally announced before 3, 4, and 5 were even released. Again, all of this is highly suspect with all things considered.
You do realize promotions don't have to happen on exactly the same release date as the game, right? Three Houses has a huge DLC coming out that they literally dropped a trailer for right with the Byleth presentation and Nintendo games drop in price so infrequently that it literally wouldn't matter if they did Byleth a year from now or not because Three Houses sales are still going to make Nintendo that good good money.
-The lack of Koei Tecmo costumes isn't suspicious. Just because Koei Tecmo helped make Three Houses does not mean that they will release costumes with Byleth DLC and the Mii costumes with Byleth further prove that there don't have to be any connections that Banjo & Kazooie already established. Costumes don't have to make sense, nor was there any reason outside of a baseless assumption to think they would show up with Byleth.
-The further that Byleth is in the past, the more time Sakurai has to familiarize himself with the game and develop the content around the fan reaction and true final build. It makes plenty of sense for Byleth to release a few months after Three Houses' release. Half a year in game development isn't that much later either to be honest. And as I said before, they have DLC that can be promotional and Three Houses will still sell well and make Nintendo happy, maybe even selling well past the initial release because Nintendo likes its "evergreen titles" so much. Plus, this also presumes that the
only reason Byleth was added was promotional, and that's just a way too cynically minded take when Sakurai clearly found inspiration in creating a moveset for them. It all makes plenty of sense.
-Again, you're assuming Three Houses needs to come with Mii costumes and that they specifically have to release with Byleth if they're coming and not in general. Which remains on shaky ground at best considering Nintendo seems to not really care.
-He was only the end of the originally planned DLC if things didn't go well for Nintendo. They clearly always intended to re-evaluate like any good business after they saw how things performed and more DLC seemed to almost always be on the table from Sakurai's comments. It seems like we were likely to at least get 1 or 2 more fighters if they hadn't gone with a full Volume 2.
-Sakurai likes to keep secretes and is probably pissed that so much has leaked for Ultimate beforehand. You can't really blame him for trying to keep one secret during DLC with the one character whose information he could absolutely control the most since it was a first party.
-More DLC gets people excited regardless of when it gets announced and its clear they wanted to announce it alongside Terry to give that whole presentation a bigger boom. Smash was a
massive part of that September Direct and was why so many people walked away so happy from it. It makes perfect sense to have been announced in that context as well.
You're just building an unnecessarily complicated theory with tons of unfounded assumptions and leaps in logic again.
